This study is a prospective, multicenter, and exploratory study aimed at evaluating the effectiveness of Huaier Granules in preventing postoperative recurrence and metastasis of colorectal cancer.
Phase II, multicenter, open-label, multi-cohort proof-of-concept study designed to evaluate the safety and efficacy of Ezabenlimab combined with BI 907828 in patients with unresectable, locally advanced or metastatic solid tumors.
Precision oncology aims to improve clinical outcome of patients by offering personalized treatment through identifying druggable genomic aberrations within their tumors. This is particularly valid when it comes to offering alternative treatment options for patients with advanced tumors that are chemo-refractory. Patient-derived organoids (PDOs) are 3 dimensional tumoroids that can be expanded ex vivo and are both pheno- and genotypically identical to patients' tumors. Observational studies have shown that PDO-based drug screens can predict treatment response with high sensitivity and specificity. Vlachogiannis G. reported a living biobank of patient-derived organoids (PDOs) from patients with advanced GI cancers enrolled in clinical trials. PDOs can recapitulate patients' clinical response to chemotherapeutic agents. In 19 tumor organoids, the group performed molecular profiling and drug screens and then compared ex vivo organoid responses to anticancer drugs. Drug response to PDO based orthotopic mouse tumor xenografts correlated to the drug response of the patient in clinical trials. Further to the study, there were other retrospective validation studies utilizing PDOs from patients enrolled in clinical trials such as the TUMOROID, CinClare to predict clinical response. Ooft studied PDOs from patients with metastatic colorectal cancers enrolled in the TUMOROID study to predict response to irinotecan-based therapies. Yao generated a organoid biobank of 80 locally advanced rectal cancers. These patients were derived from a phase III study (CinClare) that compared neoadjuvant chemo-radiation using either capecitabine or CAPIRI. Response to chemoradiation in patients matched to that of rectal cancer organoids (sensitivity 78% and specificity 91.9%). In a systematic analysis of 17 studies (9 on advanced GI and pancreatic cancers, one on renal cell cancer and others on miscellaneous cancers), the pooled sensitivity and specificity for discriminating patients with a clinical response through PDO-based drug screen was 0.81 (95%CI 0.69-0.89) and 0.74 (95%CI 0.64-0.82) respectively. Within 4-6 weeks, PDO-based drug screen creates a true personalised platform by predicting patient-specific drug response with high accuracy. Recent technical advancements in growing these PDO 'avatars' from biopsies have made it possible to test suitable anticancer drugs in patients with advanced inoperable tumors, and explore the new possibilities for treatment options that otherwise would be missed by standard conventional therapies. In 2019, our group embarked on PDO research; investigators obtained tissues from patients with advanced/ inoperable solid tumors, and performing drug screens on these PDOs ex vivo. In several patients, investigators were able to identified drugs not otherwise used through sequencing data, and observed remarkable clinical response in patients with PDO responsive tumors. Investigators illustrate with cases that underwent PDO culture and drug screens. [ See appendix ] In the literature, the clinical utility of treatment based on PDO informed drug options has however not been fully established. Investigators therefore propose a phase 2 proof-of-concept clinical trial to evaluate efficacy of NGS/ PDO guided treatment in patients with inoperable or metastatic solid tumors..
Robotic right hemicolectomy with intra-corporeal anastomosis may have better short-term recovery outcomes and decreased incidence of incisional hernia when compared to the laparoscopic actual standard of care, for similar safety outcomes.
This study is a prospective, multicenter, randomized controlled clinical trial to evaluate the safety and efficacy of polyvinyl alcohol sodium acrylate embolization microspheres and HepaSphere Microspheres loaded with irinotecan for the treatment of colorectal cancer with hepatic metastases through arterial chemoembolization.
Health establishments encourage the development of specific care pathways for the elderly by supporting Geriatric Peri-Operative Units (GPOU). Indeed, this shared care model has shown a clear reduction in mortality and the number of re-hospitalizations in patients 6 months after their care. The multidisciplinary approach of global management of the patient in the perioperative period aims to reduce surgical stress as well as the rapid restoration of previous physical and psychic abilities. Colorectal surgery, the main treatment for stage I to III colon cancer, is a morbid surgery. Despite numerous efficacy data on improved rehabilitation after colorectal surgery, care programs are not specific to the geriatric population and geriatric assessment criteria to describe the functional status of patients are not commonly used. The study investigators wish to evaluate the impact of GPOU treatment following colorectal surgery, on the evolution of several clinical parameters such as: functional status, morbidity mortality, quality of life, and lifestyle. The study investigators hypothesize that management in the GPOU for colorectal cancer surgery in patients aged 70 and over will improve functional status at 3 months, in comparison with traditional management. The proposed intervention should also lead to an improvement in patient satisfaction with care, complications and re-hospitalizations, nutritional status, lifestyle and patient survival.
The aim of this clinical trial is to learn about efficacy of fruquintinib combined with serplulimab in patients with microsatellite stabilized mCRC who have failed standard therapy. The main purpose is to explore efficacy, safety and tolerability of the treatment. At the same time, the correlation between biomarkers (including ctDNA, TPS, CPS, tumor mutation burden, lymphocyte subpopulation, cytokines, TCR, intestinal microbes, etc.) and the efficacy and drug resistance mechanism will be analyzed, which could provide reference for determining the advantaged group.
For patients with initially resectable colorectal cancer liver metastases who have high-risk factors, neoadjuvant therapy is currently considered a consensus approach. However, there is ongoing debate regarding the optimal treatment strategy. Our study aims to investigate whether the addition of cetuximab to neoadjuvant chemotherapy improves outcomes compared to neoadjuvant chemotherapy alone. The objective of this phase III clinical trial is to determine whether the combination of cetuximab and mFOLFOX6 chemotherapy is superior to neoadjuvant mFOLFOX6 chemotherapy alone for patients with initially resectable colorectal cancer liver metastases who have wild-type RAS/BRAF and high-risk factors.
This study will evaluate the safety, and tolerability of Cadonilimab as neoadjuvant treatment for resectable local advanced colorectal cancer patient with dMMR/MSI-H.
